    • An error correction code of the product sign format is added to the input information data to form coded data. The coded data are then NRZI converted and recorded onto a record medium together with identification data of a predetermined data pattern. Error detecting and correcting processing is executed with reproduction data obtained from the record medium to reproduce the data recorded on the record medium. The device comprises an NRZI converting circuit for outputting the information data as they are without NRZI converting the same but for NRZI converting the coded data using the last bit of the identification data as an initial value, and a memory controlling circuit (501) for controlling writing and reading of a memory, which is provided to convert the reproduction data from a series of inner codes into another series of outer codes, so that write address information for the memory which is obtained from the reproduction data may be compensated for when it is not obtained properly and outer code error detecting and correcting processing may be executed in a trouble-free way.
    • 将产品符号格式的纠错码添加到输入信息数据中以形成编码数据。 然后将编码数据与预定数据模式的识别数据一起NRZI转换并记录在记录介质上。 使用从记录介质获得的再现数据执行错误检测和校正处理,以再现记录在记录介质上的数据。 该装置包括:NRZI转换电路,用于按照原样输出信息数据,而不进行NRZI转换,而使用识别数据的最后一位作为初始值对编码数据进行NRZI转换;以及存储器控制电路(501),用于控制 存储器的写入和读取被提供以将来自一系列内部代码的再现数据转换成另一系列外部代码,使得可以补偿从再现数据获得的用于存储器的写入地址信息 无法正确获取,并且可以以无故障的方式执行外码错误检测和校正处理。

    • Simplified decoding procedures based on trellis diagrams are given for lattices and codes. In one arrangement, for selecting a codeword near to a given N-tuple r, the codeword representing a point in an N-dimensional lattice, the N-tuple r comprising a sequence of N real values r i representing signals, the values r of the N-tuple r being organised into n sections r ; respectively of lengths N j , I ≦ j ≦ n, where n ≧ 3, and N j j , I ≦ j ≦n.Each such substage of the first stage comprises means for evaluating distances between multiple sets of possible partial codewords and the section r j , these partial codewords comprising the corresponding N of the symbols appearing in a subset of said codewords. Additionally, each first stage substage has means for selecting as a survivor from each of the multiple sets one of the partial codewords. The selection is based on the distances. Each substage also includes means for providing to the second decoding stage information indicative of each of the multiple survivors and its distance. The second decoding stage comprises n-I substages. Each such substage of the second stage corresponds to a supersection made up of a combination of two parts, each such part being a section or a supersection combined in an earlier substage of the second stage, a final such substage corresponding to a final supersection whose parts make up the complete N-tuple r. Each substage of the second stage except the final substage comprises means for evaluating distances between multiple sets of possible partial codewords and the received values in the corresponding supersection. This evaluation is based on the information indicative of survivor distances for the survivors corresponding to each of the two said parts. Each substage of the second stage other than the final substage also comprises means for selecting as a survivor from each of the multiple sets one partial codeword on the basis of the distances, and for providing information indicative of each of the multiple survivors and its distance to subsequent decoding substages of the second stage. The final substage comprises means for evaluating distances between said codewords and the N-tuple r. This evaluation is based on the indications of survivor distances for survivors corresponding to each of two of the parts. The final substage also includes means for selecting one codeword as a finally decoded codeword based on the distances between codewords and the N-tuple r, and for providing information indicative of the finally decided codeword as an output of the decoder.
